Cedar COB LEDs' waterproof, shockproof, static free, anti-oil stain, excellent heat dissipation, wide view angle, signal/power backup etc. features make it invincible for control center, conference, TV, subway, large scale events, education, medical diagnosis, advertising etc. applications.
World's first outdoor use COB LED display was developed by Cedar in 2007, mass production of 1.25mm fine pitch COB LED started in 2014, new generation flip-chip COB was launched in early 2018, P0.5 will come out in 2019, we have been updating and improving.

COB display is sealed by epoxy resin and has no bare pad, which protects the LEDs from water, dust, oil stain, collision and static.

3. High Gray Scale

With high precision control technology and high-end driving IC, COB LEDs can achieve high color depth even under low brightness to make the images smoother and more vivid.

4. Wide Viewing Angle

175°H/175°V wide viewing angle, no color shift and seamless in all directions.

5. Patented Dot by Dot and On-site Calibration

World’s first and most advanced dot by dot and on-site brightness and color calibration technology to contribute the best uniformity of whole screen.

6. Area Light

COB adopts high filling rate optical design to form an area light, more uniform without glare, suitable for 7x24hrs long time close viewing. Unique matte coating increases image contrast and reduces light radiation, no moire.
